Abstract

An apparatus for picking up, transporting and exactly depositing planar work pieces, particularly cloth parts, comprises lifting devices which can be moved over work piece deposition points. The lifting devices comprise a pressure plate having a plurality of adhesive-tape pickups removably fixed thereon, e.g., by adhesion magnets. The adhesive-tape pick ups can be easily moved to any number of selectable points on the pressure plate in order to conform to the work piece to be picked up. The adhesive-tape pickups comprise a tubular housing having disposed therein a longitudinally movable adhesive-tape winding device with associated table deflection rolls. The tubular member has a baffle plate located at the bottom thereof. The baffle plate is provided with apertures. The tape deflection rollers protrude slightly through these apertures presenting adhesive tape for picking up a work piece when the apparatus is positioned at a pickup point. When the apparatus is positioned at a workpiece deposition point, lowering of the pressure plate at the deposition point causes the tape deflection rollers to be retracted within the apertures and work piece is stripped off by the baffle plate.

Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of Application The present invention provides a method for receiving and transporting sheet-shaped workpieces, in particular fabric parts, between at least one first and second loading point. and precise loading device in the form of an adhesive tape receiving device, which has a running or rotating platform with at least one lifting device that bridges the loading point, the lifting device working on the adhesive principle. The adhesive tape receiving device has an adhesive tape winding device movable longitudinally in a holder guided in the frame, the adhesive tape winding device being provided on the bottom side of the frame. , a tape deflection roller forming an adhesion roller, and a frame with an aperture suitable for projecting the adhesive tape in the area of the tape deflection roller towards the release plate when the adhesive tape winding device is in the receiving movement position. The bottom has a holder, and the adhesive tape winding device is the first to control the moving position of the adhesive tape winding device up and down in consideration of the gradual conveyance of the adhesive tape. When the lifting device lowers at one of the loading points, the adhesive tape grips the workpiece to be conveyed in the area of the adhesive roller, and the workpiece to be transported is held in the lifted position while the lifting device is being conveyed. The device is of the type that is released again after being lowered at the second loading point.

Devices of this type, which are known from the prior art, for example from US Pat. No. 3,083,961, are useful for automating partial processes in industrial production areas. Automation is especially important in the field of ready-made clothing manufacturing. This is because wages in this manufacturing field are still higher than in other manufacturing fields, and rationalization is essential to lower costs.

Division [Clothing and Knitted Products J 22 (1983) No. 13 No. 6
As described on pages 11 to 11, great difficulties arise when stacking the fabric sections. This means that such a flat workpiece can be successfully received from a workpiece nozzle and placed again in a predetermined condition, for example on a chisel, for further machining at another location. Receptor devices operating on the aerodynamic principle are only able to accept and convey satisfactorily textile surface elements with sufficiently low air permeability. Furthermore, an advantageous receiving device working on mechanical principles uses the glyph-q system, which is equipped with a receiving needle or a tightening device. However, in practice, such gripper systems are not very reliable and may not be able to satisfactorily adapt to the significantly different material properties of such planar workpieces.

Furthermore, in the case of receivers that work on the adhesion principle, differences in material properties are not a problem, but they are accompanied by other problems. This is because the adhesion force decreases as the usage period increases, and the adhesion surface becomes dirty.

In this case, therefore, only an adhesive tape receiving device with an adhesive tape winding device can be used in order to keep the adhesive surface fresh during the working process. U.S. Patent No. 30839
Furthermore, the adhesive tape receiving device disclosed in '61 has a relatively bulky and complex structure. It is therefore not possible to adapt this receiving device to the different dimensions of the workpieces to be received. However, in the field of ready-to-wear manufacturing, a high degree of flexibility is required of such receiving devices. This is because the workpieces present as fabric sections vary considerably in size and dimension.

Problem to be Solved by the Invention The problem to be solved by the invention is that the device mentioned at the beginning can be improved and adapted to planar workpieces of arbitrary shape at relatively little expense. It is an object of the present invention to provide a device equipped with an adhesive tape receiving device that can be operated reliably.

Means for Solving the Problem A further means for solving the problem according to the invention is that in an apparatus of the type described above, the lifting device is a pressure plate which can be moved up and down by a drive in the vertical direction, and the adhesive tape receiving device is The device is divided into a plurality of adhesive tape receiving devices forming independent functional units, the adhesive tape receiving device having a tubular casing which can be attached to the underside of the pressure plate by means of fastening means. It is possible to fix it vertically in this arrangement.

The present invention achieves a high adaptability of the receiving device to the shape of the workpiece to be received by dividing the receiving device into a plurality of tubular receiving devices each forming an independent functional unit. Because it has functionality, it can be fixed to the pressure plate forming the common bottom plate in any arbitrary arrangement in practice, and because of its finger-like shape, it hardly interferes with the mutual arrangement relationship. The starting point is that it is extremely simple and advantageous to be able to adapt the overall arrangement of the pressure plate to the shape of the planar workpiece.

Embodiment According to one advantageous embodiment of the invention, there is provided a device for automatically placing planar workpieces to be fixed onto each other on the press inlet side formed by a feeding device for a fixing press. On each side of the feed device forming the second loading station, a first loading station, preferably in the form of a magazine for milling the workpiece to be machined, is provided; A carriage bridging two loading points is arranged on a carriage movable along the carriage, one behind the other in the running direction, with a distance between the second loading point and the first loading point. In addition, two lifting devices are provided whose movement courses are synchronously controlled. With this configuration, one workpiece is placed on the second loading point each time the carriage moves, whereas one workpiece is placed on one of the two loading points during each loading process. The receiving process will also take place at the same time.

Particularly advantageous is a magazine which is accessible from above and whose first loading point receives the workpiece ξ, the lateral limits of which are oriented laterally and slightly downwards. This is done by means of a brush with bristles, which is fixed to the brush element by means of adhesive magnets at any selectable point on the bottom plate containing iron, for example a steel plate, in order to adapt the brush element to the contour of the workpiece pile. It should be possible to fix it.

Extensive experimentation with the present invention has shown that adhesive tape receivers whose number and location on the pressure plate are matched to the contour of the workpiece to be received can be mounted on the workpiece using a brush magazine of predetermined dimensions. Suitable for neatly individualizing workpieces. The reason for this is that not only the number and position of the adhesive tape receiving devices, but also the number and position of the brush elements forming the brush magazine as a whole, can be adapted perfectly to the contour and size of the workpieces assembled in a This is because it is possible.

Further advantageous embodiments of the brush magazine according to the invention are indicated in the claims 4 and 5.

The continuous operation of the adhesive tape winding device integrated in the adhesive tape receiving device, which is necessary during the course of operation, is carried out during the movement of the adhesive tape winding device in the tubular casing between the receiving transfer position and the peeling transfer position. It is advantageous to do so. An advantageous embodiment of this reservoir is described in patent claim 6.

The adhesive tape in the adhesive tape winding device becomes unusable during the course of operation and must be replaced from time to time. It has therefore proven advantageous to design the adhesive tape winding device as a replaceable unit that can be inserted into a guided holder. For this purpose, the interior of the tubular casing is made accessible by a suitably designed removable lid.

According to a particularly advantageous embodiment of the adhesive tape receiving device, the guided holder of the adhesive tape winding device is connected on the pressure plate side to the piston rod of a small compressed air cylinder arranged in the tubular housing. , this compressed air cylinder is connected via an electrically controllable air valve and an air hose to a compressed air distributor arranged on the pressure plate. In this case, the control of the compressed air cylinder is carried out in a suitable manner to the movement of the lifting device.

Particularly simple assembly is achieved when producing such an adhesive tape receiving device by using a compressed air cylinder as a displacement drive for the adhesive tape winding device. Furthermore, such a compressed air cylinder makes it possible to adjust the pressure of the adhesive tape on the workpiece over a wide range, so that the adhesion can be adjusted as required for different materials of the workpiece.

Furthermore, such compressed air cylinders allow stroke adjustment over a relatively wide range.

In the case of adhesive tape receiving devices working with such compressed air cylinders, the compressed air distributor must also be connected to the width and/or length of the pressure plate to ensure any placement on the pressure plate with as short a connection hose as possible. It is advantageous if the distributor strip extends along the edge and has a number of quick connections for the air hoses to be connected.

Further advantageous embodiments of the adhesive tape receiving device are described in the patent claims 10 to 12.

EMBODIMENT OF THE INVENTION The apparatus shown in FIGS. 1 and 2 on the inlet side of a stationary press has a frame-shaped carriage 1. FIG. This running platform 1

Two lifting devices H1 and H2 are arranged one after the other on the carriage 4 at a distance from the first mounting points Ala and Alb to the second mounting point A2. These elevating devices H1 and H2 each have a piston rod 61 of a vertically oriented compressed air cylinder 6 fixed on its upper surface, and a plurality of fixing members on its lower surface, which can be fixed in any position via fixing members, preferably magnets. It has a pressure plate DP with an adhesive tape receiving device KA. It is also possible to use a high-speed chuck as the fixing member, which engages in one of a number of openings in the pressure plate with a grid of holes. The pressure plate with the hole grid also makes it possible to fix the adhesive tape receiving device KA with screws.

The compressed air cylinders 5 and 6 forming the pneumatic drive are controlled by electrically controllable valves (not shown). In FIG. 1, the carriage 4 is shown in its left-hand end position, and the lifting devices H1 and H2 are shown in a downward movement. At this position, the adhesive tape Aigo device KA of the lifting device H1
receives a workpiece, for example a cloth part, from the workpiece pile of the magazine 31 at the first loading point Ala;
The lifting device H2 at the operation start position has not yet performed its loading function.

In the next working stroke, the pressure plates DP of both lifting devices H1 and H2
performs an upward stroke, and the compressed air cylinder 5 is moved by the carriage 4.
to the right end position (see FIG. 2). Next, by lowering the pressure plate DP, the fabric portion received from the first loading point Ala is placed on the 20th loading point A2 by the lifting device H1, and at the same time, the lifting device H2
10th mounting point Alb by the adhesive tape receiving device KA of
A workpiece, for example a stationary insert, is received from the workpiece pile in the magazine 32 at. Both lifting devices H1 and H2
After the pressure plate DP of has been raised and the carriage 4 has been moved via the compressed air cylinder 5 to the left end position shown in FIG. 1, the lifting devices H1 and H2 are lowered again and the lifting The fixed insert, which attaches to the free end of the adhesive tape receiving device of the device H2, is placed exactly on the fabric part already placed in the second placement point A2. At the same time, the adhesive tape receiving device KA of the lifting device H1 again receives a workpiece from the workpiece A file of the magazine 31. Each time the carriage is moved in this manner and both lifting devices H1 and H2 are raised and lowered, one workpiece is received at the first loading point and placed at the second loading point. be done. When the two workpieces to be fixed together are placed on the second mounting point A2, the conveyor belt forming the second mounting point A2 is moved and transports the fabric parts to be joined together to the press. do.

As shown in more detail, a preferred embodiment also has a compressed air cylinder for moving the adhesive tape winding device on the adhesive tape receiving device. This compressed air cylinder, like the compressed air cylinders 5, 6, is actuated via an electrically controlled valve and is connected via a hose line to a compressed air distributor. In this case, such an adhesive tape receiving device is attached to the pressure plate D.
A distributor strip extending on the edge side over the width and/or length of the pressure plate in order to allow relatively short hoses to be required for freely selectable fixation on the PO surface. A compressed air distributor in the form of is provided.

This distributor strip is designated by the symbol V in the lifting device H2 of FIG.
Indicated by L.

This distributor strip VL is shown in perspective view in FIG.
It has two metal rods 7 positioned one above the other. This metal rod 7 has a hole 71 and a connecting screw 72 in its longitudinal direction, and a row of quick connections 73 distributed in its longitudinal direction. This quick connection 73 is connected to an axial hole in the metal rod 7.

One embodiment of the adhesive tape receiving device KA, which is shown in cross section in FIGS. It is closed by a plate 10 in which is embedded an adhesive magnet 11 which is fixed to the pressure plate. At the edge of the plate 10 there is a compression thrust cylinder 9 for moving the adhesive tape winding device from the upper peeling position shown in FIG. 4 to the lower receiving position shown in FIG. It is fixed via an intermediate plate 12.

At the same time, a holder 13 of an adhesive tape winding device KW is guided on this intermediate plate 12. At its lower free end, the tubular casing 8 has an end plate 81 which has an opening 82 through which a deflecting roller 14 as an adhesive roller protrudes, which is arranged on the underside of the adhesive tape winding device. are doing. Furthermore, adhesive tape winding device KVI71! In addition to the small deflection roller 14a disposed between the deflection rollers 14, one adhesive tape payout zebin 17 and one adhesive tape winding bobbin 18 are rotatably supported on pins 15 and 16 one above the other. have. A gear wheel 19 is provided which is rigidly connected to the adhesive tape winder 18 and is rotatable on the pin 16. This gear 19 is in the form of a locking device and the teeth of the gear 19 are connected to a driver 20 fixed to the tubular casing 8 when the adhesive tape winding device KW moves from a lower receiving position to an upper peeling position. After peeling off one workpiece in such a manner that it moves from the first mounting point to the second mounting point over a range of rotational angles determined by The deflection roller 14, which is closely connected to the workpiece during receiving and conveying to the location, is used by the deflecting roller 14 (which is conveyed first and is constantly used in the successive receiving and loading processes). No adhesive tape is now provided for receiving the workpiece.

In relation to FIG. 1 and FIG.
2, when the lifting device H1 of FIG.
In order to receive a workpiece from a file of workpieces, the adhesive tape winding device is brought from an upper stripping movement position to a lower receiving movement position. In this lower receiving position, the deflection roller 14 together with the adhesive tape KB slightly protrudes through the opening 82 of the end plate 81 and is pressed onto the workpiece to be received when the lifting device H1 is lowered further. . At the start of the lifting of the lifting device H1, the adhesive tape winding device remains in the lower receiving position, and the lifting device H1 reaches the second loading point A2, as shown in FIG. 2, and begins the next lowering stroke. until it is lowered onto the second mounting point. Next, while the lifting device H1 is lowered, the adhesive tape winding device KW is moved from the lower receiving movement position to the upper peeling movement position. As shown in FIG. 5, the driver 20 now meshes with the gearwheel 19, and the aforementioned feeding of the adhesive tape KB takes place during the upward movement of the adhesive tape winding device KW. At the same time, the end plate 81 of the tubular housing acts as a stripper of the workpiece adhering to the adhesive tape KB in the area of the deflection roller 14.

The adhesive tape KB is carried out during the upward movement of the adhesive tape winding device KW by selecting the number of teeth of the gear 19.
The transport length is specified.

The consumption of adhesive tape KB during operation occasionally requires replacing the used adhesive tape roll with a new adhesive tape roll. In order to make this connection as simple as possible, the adhesive tape winding device is replaceably inserted into a guided holder 13 with a gear wheel 19 and a pin 16, as shown in one embodiment in FIG. It is advantageous to configure it as a possible unit E. In this case, the unit E has a holding plate 21, on which the deflection rows 214 and 14a, the adhesive tape feeding zebin 17 and the adhesive tape winding zebin 18 are held one above the other at predetermined positions. ing.

In this case, adhesive tape payout Zebin 170 rotating pin 1
7 is fixed to a holding plate 21 and has a corresponding bearing 22 on the guided holding body 13. Correspondingly, deflection rollers 14, 14 are rotatably mounted on the bin 23.
This also applies to a. The corresponding bearing is designated 24 in FIG. Furthermore, the gearwheel 19 has entrainment pins 25 on both sides of the pin 16. This entraining bin 25 is located in a suitably arranged recess in the adhesive tape winding bin 18 (not shown in FIG.
It engages when inserted into the

As further shown in FIG. 6, the tubular housing 8 is divided into a housing part which is fixedly connected to the guided holder 13 and a removable lid 8a. With the unit E inserted into the guided holder 13, the lid 8a engages with its upper end in the groove 26 of the plate 10. Furthermore, the bottle 16 projects through an opening 27 in the unit E and in the lid 8a, with a thread at its free end making it possible to fix the lid 8a to the casing part by means of a screw nut 28.

7 and 8 show two variant embodiments of an adhesive tape winding device designed as an exchangeable unit (E). The unit E shown in FIG. 7 corresponds to the embodiment shown in FIGS. 4 and 5 and has in each case one large deflection roller 14 on each side of the lower part, arranged between small deflection roller 14 shifted inwardly
A is provided. In this case, the outer periphery of each deflection roller 14 is provided with a bonding point for receiving the workpiece.

The embodiment of FIG. 8 is particularly suitable when the planar workpiece to be received requires a large adhesive surface due to its own weight. This is because the central deflection roller 14a is configured to be large.
This is achieved by stretching the original adhesive tape KB between the deflecting rollers 14 as a support. In the embodiment of FIG. 8, the end plate 81 of the tubular casing 8, in contrast to FIGS. 4 and 5, is provided with only one rectangular opening extending between the deflection rollers 14.

Another advantageous embodiment of the adhesive tape receiving device shown in FIGS. 9, 10 and 11 is similar to the embodiment of the adhesive tape receiving device shown in FIGS. It is closed on the pressure plate side by a pressure hood 1' 3c, in which the tubular casing 8 is held in telescopic manner, and the pressure is applied against the force of at least one spring element 40 or 41. It differs in that it is movable toward the bottom of the hood 8c. In this case, the bottom of the pressure hood 8C consists of a metal plate 10 and an adhesive magnet 11 embedded therein, in accordance with the embodiments of FIGS. 4, 5 and 6. Furthermore, these three embodiments differ in that the guided holder 13a or 13b or 13c of the adhesive tape winding device KW is constructed somewhat differently and in each case has a further spring element 40a or 418. This differs from the embodiment shown in FIG. This further spring element is such that the adhesive tape winding device KW can only be brought from the lower receiving position into the upper peeling position against this spring force via the guided holder 13a or 13b or 13c. It acts on In this case as well, the adhesive tape KB is conveyed in a tubular manner when the adhesive tape winding device KW moves from the lower receiving position to the upper peeling position, as in the embodiments shown in FIGS. This takes place in that a driver 20 fixed to the housing 8 meshes with a gearwheel 19 which is rigidly connected to the adhesive tape winder 18.

In the embodiment of FIG. 9, the movement of the adhesive tape winding device is possible by means of gear wheels 42 and 43 which are fixedly connected to one another. These gears 42, 43 are rotatably supported on pins 44 on the upper side of the guided holder 13a;
It constitutes a locking member. A rack 45 fixed to the bottom of the pressure hood meshes with the gear 42 from the left side, while a rack 45 fixed to the holder 13 & guided from the right side meshes with the gear 43. In the gear 44, the tooth ring has teeth in successive 90° sectors and teeth without teeth. This 90° sectoring is carried out by both gears at the end of the lowering movement of the lifting device.
000 Determine the rotation angle.

In the embodiment according to FIG. 9, the adhesive tape winding device KW is in a lower receiving position. In this receiving and moving position, the workpiece adhering to the adhesive tape KB in the area of the deflecting roller 14 is transferred from the first placement point A1a, AI, b to the second placement point A.
2. When the lifting device H1 or H2 is lowered and the adhesive tape receiving device KA is placed in the second mounting point A2, the tubular casing 8 is pushed into the pressure hood 8C, in this case via the rack 45. Gears 42 and 4
3 is rotated 90 degrees in a predetermined rotation direction. The holder 13a guided at this time passes through the rack 46 to the gear 4.
4, so that at the same time as the tubular casing 8 moves, the adhesive tape winding device KW is also moved from the lower receiving movement position to the upper peeling movement position. The adhesive tape winding device KW remains in this upper peeling position until the lifting device is lowered again onto the first mounting point Ala or Alb. In this case, the casing 8 is connected to the end plate 81.
If the tubular casing 8 is pushed into the pressure hood 8c again during the subsequent lowering of the lifting device, it is now supported by the rack 45 on the workpiece pile of the magazine 31 or 32 on one side of the gear 42. 43 is rotated, the meshing between the rack 46 and the gear 44 is released, and the adhesive tape winding device KW is moved to the guided holder 1.
3a and moves from the upper peeling movement position to the lower receiving movement position to receive another workpiece under pressure from another spring member 408. Next, the lifting device moves to the second mounting location A2.
At the end of the upward and downward movement, the rack 46 is moved by the further rotation of both gears 42 and 44
At this point, the adhesive tape winding device KW is again moved upward to the peeling movement position.

In the embodiment shown in FIG. 10, moving the adhesive tape winding device in conjunction with the lifting movement of the lifting device includes:
It is carried out using rope 47. This rope 47 is shortened by a spreading device 49 in the form of a rotary bender controlled by a switching gear 48 in order to raise the adhesive tape winding device KW. In Figure 10, the expansion device 4
9 is brought into operation in the illustrated position of the switching gear 48. Therefore the rope 47 achieved by this
Due to the shortening of the adhesive tape winding device KW, the adhesive tape winding device KW is moved upward to the peeling movement position. When the lifting device is lowered onto one of the first mounting points A1g or Alb shown in FIG.
When pushed into the pressure hood 8c, the switching gear cow 8
is switched into the next switching position by means of a push rod 50 fixed to the bottom of the device ζ, and the spreading device 49 is brought into its inactive position, whereby the rope 47 is lengthened and the adhesive tape winding device KW is guided. The holding body 13b is moved from the upper peeling movement position to the lower receiving movement position by the force of another spring member 418. During the subsequent movement of the pressure hood 8c during the downward movement of the lifting device onto the second mounting point A2 in FIG. position, and the adhesive tape winding device KW is brought back into the upper peeling movement position in order to carry out the desired peeling.

Furthermore, in FIG. 11, an unlocking device 52 which can be controlled by a switching gear 51 is provided above the guided holder 13e for the adhesive tape winding device KW. In this case, the switching gear 51 is driven in the form of a locking device when the pressure hood 8c is moved relative to the tubular casing 8 by means of the push rod 5o, as in the embodiment according to FIG.
In the second pass, the elastic locking finger, which is also fixed to the bottom of the pressure hood 8c, is moved to the corresponding locking member 5 on the upper side of the guided holder 13e for the adhesive tape winding device KW.
4 to the inactive position.

In the position of the adhesive tape winding device KW shown in FIG. 11, that is, in the upper peeling movement position, the locking between the locking finger 53 and the corresponding locking member 54 is effective. If the pressure hood 8C moves relative to the tubular casing 8 when the lifting device is lowered to the second mounting point A2 in FIGS. The guided holder 130 is then lifted up against the force of the other spring element 41a during the lifting of the lifting device together with the adhesive tape winding device KW. The lifting device is located at the first mounting point Al
When the pressure hood is moved relative to the tubular casing 8 during the next descent into one of A or Alb, the switching gear 51 is switched so that the locking finger 53 is moved into the corresponding engagement as indicated by the dashed line. It is removed from the stop 54,
The guided holder 193C is lowered again to the lower receiving movement position together with the adhesive tape winding device KW by the force of the other copying member 41a.

Width 12, density 1.38/y-me, length 25 with this width
A PVC tape with an adhesive strength of 225 pounds has been found to be suitable.

In this case, such an adhesive tape can be accommodated in the adhesive tape winding device KW in a length of 30 m, taking into account the small dimensions of the adhesive tape receiving device KA.

As already pointed out, a good working style of a lifting device with a receiving device is difficult at the loading point in the magazine. It is relevant to individualize and receive from such piles without any problems. FIG. 12 shows one of the magazines 31, 32 which allows perfect individualization. This magazine 31,32 consists of a brush element 56 with bristles facing the workpiece pile 30. Approximately 20 bristles
It is directed downward at an angle of '. Brush member 5
In order to adapt the brush element 6 to the contour of the workpiece pile, the brush element 56 has an attachment magnet 57 on its foot side so that it can be fixed at any point on the magazine bottom, which is made of a steel plate 58, for example. As shown in practice, the brush member 56 advantageously has a length of 20 mm and a thickness of 0.10 to 0.2' Omm. This is because such pig hair has high flexibility.
